Description

Adjustable mounting device and sliding device for sliding elements

The present invention relates to an adjustable mounting device for a sliding element, in particular a sliding door held by two brackets slidably held within a running track, and also to a sliding device having such a mounting device.

A mounting device for this purpose is known from [1], EP 0 818 598 A1. Such a mounting device includes a retaining track connectable to the sliding door and for receiving the retaining device, which is coupled to the bracket by bolts. The retaining rail is inserted into the recess, and the recess is provided on one end of the upper side of the sliding door. The retaining device includes a retaining block that is retained in the retaining track in a form-locking manner, is axially movable within the retaining track, and can be secured at a desired location by the edge. This fixed position is selected in such a way that the carriage reaches the position of the damper device provided in the running track at which the sliding door is displayed as the desired distance from the door frame. However, if the retaining block is not fixed at this position, the sliding door will reach the door frame before the bracket reaches the bumper device, or be held a greater distance from there, making the unwanted between the door frame and the sliding door The gap remains open.

In the retaining block, the head of the connecting bolt is rotationally held and can be fixed by fixing bolts. In order to align the upper edge of the sliding door and thereby adjust the connecting bolt, this requires moving the retaining block out of the retaining track until the fixing bolt can be released, and the connecting bolt can be clamped and rotated using a tool. After adjusting the connecting bolt, in order to obtain the desired distance between the sliding door and the door frame, the holding block is again moved into the holding rail and fixed at a predetermined position. Therefore, time and technology are required to accurately control the process of installing the device.

[2], WO2011063535A1 discloses a mounting device having a holding rail for receiving a holding device connected to a bracket by a connecting bolt. In this case, only the connection bolt needs to be adjusted when the holding device is taken out of the holding rail.

[3], WO 2011161707 A1 discloses a mounting device having a connecting bolt with a bolt head that is vertical to the adjusting bolt. By turning the adjusting bolt, the connecting bolt can be guided along the wedge and thus moved horizontally and vertically. Therefore, after adjusting the height, it is necessary to readjust the end position of the sliding door.

[4], WO9738198A1 and [5], DE 3 338 146 A1 also discloses a mounting device that requires re-adjusting the end position of the sliding door after the height adjustment is completed.

[6], WO2004040091A1 discloses a mounting device having a connecting bolt that connects a sliding door to a bracket held in a running rail. The connecting bolts that are vertically movably retained within the guide have horizontally aligned transverse bolts that are retained within the track of the track body. The main body of the rail is levelable, which causes vertical movement of the transverse bolts and the connecting bolts.

In such a mounting device, the device components are exposed to severe loads and pressures, so that after a long period of operation, wear and deformation of the constant contact components can occur.

The transverse bolts need to have a small diameter so that they can be guided through the connecting bolts. Therefore, as a high load occurs, for example, after a heavy sliding door is installed, the relatively thin lateral bolt can be flexibly bent. In addition, the transverse bolts are held by a minimum holding area having a correspondingly high holding pressure so that the guiding track is deformable. After this damage has occurred, it is no longer possible to make smooth adjustments to the device. In addition, when the connecting bolt is rotated, it can be detached from the rail main body.

It should be important to note that whether it is the overall load of the sliding door acting on the thin transverse bolts, or even greater forces, such as when the sliding door strikes an obstacle such as a track buffer, if the mounting device is not designed enough Stable, this force can cause damage to the mounting device.

There are other drawbacks as well, the connecting bolts can only move a short vertical distance, thus resulting in a small adjustment range.

Because the transverse bolts remain within the rail body, the transverse bolts can only rotate with the entire retaining device. Since the running track is typically mounted close to the building wall, this inhibits the rotation of the retaining device, so if the bracket is removed from the running track, the connection of the retaining device to the bracket is possible. However, in the case where the bracket is stably placed in the moving rail, it cannot be mounted.

Accordingly, it is an object of the present invention to provide an improved mounting apparatus that can be coupled to a sliding member and that is coupled to a bracket that is guided within the running track by an adjustable connecting bolt. In addition, it relates to an improved sliding element that is equipped with at least one mounting device of the invention.

The mounting device should be suitable for the installation of heavy sliding doors and should be operable without wear, especially without deformation. Even after a long operating cycle, the mounting device should be able to be adjusted smoothly.

Therefore, the connecting bolts should be adjustable without moving the retaining device out of the holding rail.

In addition, the mounting device should be adjusted in such a way that the connecting bolts are only moved axially and there is no need to adjust external device components, such as external damping devices.

In a more preferred embodiment, the mounting device should be designed in such a way that no external damping device is required.

This object is achieved by a mounting device and a sliding door that respectively include the features of claim 1 or 15.

The mounting device includes a connecting bolt through which the plate-like sliding member is coupled to a bracket that is movably retained within the running track. The mounting device includes a retaining rail mounted in a recess disposed at an upper side of the sliding member, the retaining device releasably retained within the retaining rail, and the retaining device including the adjusting bolt being rotationally retained In the carrying device, the adjusting bolt includes a bolt rod disposed along a bolt shaft and the bolt rod is engaged in a threaded member of the rail body, the rail body is movable along a bolt shaft and includes two rail walls, The two rail walls are aligned parallel to each other and each includes a rail member into which a guide member coupled to the connecting bolt is engaged, the connecting bolt being movably retained within the guide member along the guide shaft.

According to the invention, there is provided a track skid fitted with guiding elements on opposite sides, the guiding elements preferably being engaged in a form-locking manner within the track elements of the track body, and wherein the connecting bolts comprise a first connection, a second The connecting portion and the third connecting portion are retained in the rail sled, the second connecting portion is retained in the guiding member, and the third connecting portion is connectable to the bracket.

The use of a track skid allows for a stable connection of the connecting bolt to the main body of the track.

The guiding element preferably extends along a portion of the rail element such that the guiding element and the rail element are adjacent one another in a plane.

In this way, a relatively small supporting pressure can be generated even when a heavy sliding door is suspended from the mounting device. Deformation of the device components that can interfere with the conditioning process is avoided. Furthermore, due to the small support pressure, the adjustment process can be performed by applying a small force.

The use of a track skid allows for the advantageous mounting of a connecting bolt that can be movably mounted or rotatably mounted about a guide shaft.

It is advantageously possible to turn the connecting bolt into the bracket body without having to turn the entire mounting device. Thus, the mounting device can be attached to a bracket that is enclosed within a running track that is mounted close to the building wall.

Further, the rail skid can be easily inserted into the rail main body and stably held therein.

In a preferred embodiment, the guiding elements are held by the rail elements on both sides such that the guiding elements are not separated from the rail elements and are not rotatable. Thus, the track skid can move forward or backward in a straight line only in certain alignment situations. For example, the wing guide elements engage within the slotted track seam. Therefore, the track skid is guided and held in a straight line, and can even not move away from its orbit under the influence of force, such as when the sliding door hits an obstacle.

The retaining rail is typically mounted at one end of the upper side of the sliding element and is preferably disposed within the recess. Such a recess can be provided particularly easily in a sliding element made of wood. If, for example, when a glass door is used, no recess is provided, but the holding rail is placed in the upper side of the sliding door, for example a glass pane, and is connected thereto by known hooking elements. For example, an opening is provided in the sliding door that guides the retaining bolt through the opening, the retaining bolt being retained by a flange member that is coupled to the retaining rail.

The sliding device preferably comprises two mounting devices mounted at opposite ends of the upper side of the sliding element or sliding door and which are connected to the bracket guided in the running track. By means of the mounting device, the height of the sliding door can be selectively adjusted at both ends so that the sliding door can be raised to the desired height and level aligned. That is, the sliding door can be raised to a desired height by two mounting means preferably mounted in recesses provided at opposite ends of the upper side of the sliding door. Then, check if the upper side of the sliding door is level aligned. The residual deviation can be corrected by final adjustment of this or other mounting devices.

Adjustment of the mounting device is achieved by driving an adjustment bolt whose head faces the front side of the sliding door and can be clamped by a tool without removing the holding device from the holding rail. Therefore, the adjustment can be performed conveniently and accurately with a small amount of effort.

By rotating the adjusting bolt, the rail body is moved along the bolt axis, whereby the rail sled is raised vertically along the rail member. The track skid is held by a connecting bolt held by means of a guide and thus the track skid can be moved along a guiding axis that is generally perpendicular to the bolt axis. During the movement of the track body with the track element relative to the track sled, the track skid is raised or lowered, i.e., moved vertically along the guide axis.

The distance between the upper side edge of the sliding element and the running track changes during adjustment of the connecting bolt. However, movement of the sliding door or carriage relative to the running track in the direction of travel is avoided. Therefore, after adjusting the connecting bolt, the distance between the sliding door and the outer door frame remains unchanged after the sliding door reaches the end stop.

The carrier device comprises a holding arm having at least one retaining element that can interact with the at least one fixing element in a form-lockable manner, the fixing element being arranged on the holding rail.

The retaining track preferably behaves as a U-shaped profile having a central portion and a side wall connected thereto. Forming elements are provided on the inner side of the side wall that extend towards each other and parallel to the longitudinal axis of the retaining track. The retaining device is inserted along the forming element into the upper open retaining track and is fixed at a position where the retaining element can be engaged within the fixed element.

In a preferred embodiment, a plurality of retaining elements and/or a plurality of securing elements are provided that engage one another in accordance with movement of the retaining device within the retaining track. The retaining element and the fixing element are preferably as mutually corresponding catching elements.

In a preferred embodiment, the fixing element is provided as a connecting opening on the inner side of the central portion of the holding rail, the connecting edge or the connecting recess. For example, a set of connecting edges that behave as a connecting plane can be provided, to which complementary retaining elements can be joined at selected locations. Thus, the retaining element is designed as a hitch element, such as a cam, a connecting edge or a connecting plane.

The retaining arm is bendable such that at least one retaining element can be separated from the fixed element by the action of a force acting on the retaining arm. Thus, the retaining device can be inserted into the retaining track and automatically fixed at a predetermined position or moved to a desired position where the retaining element engages within the securing member.

The retaining arm can be released by bending. This can be easily accomplished by a functional cover that is rotatably coupled to the carrier and includes a functional lever that can be pivoted against the retaining arm when the functional cover is opened such that the retaining arm can be separated from the retaining track by force. Therefore, the retaining device can be released by hand grasping and can be separated from the holding rail.

In a preferred embodiment, the carrying device comprises a mounting flange that overlaps the associated front side of the retaining rail at the entrance of the recess and is firmly or resiliently connected to the connecting bolt. Therefore, once the carrier hits the obstacle, the kinetic energy of the sliding element can be transmitted to the connecting bolt through the retaining rail and the mounting flange and thereby transmitted to the bracket and the track buffer.

On the one hand, the tool channel is opened by a functional cover that can be rotated, for example by 90 degrees, through which the tool can be guided towards the adjustment bolt. On the other hand, the retaining arm can be driven by a preferably designed functional cover. In a preferred embodiment, the functional cover is slightly pretensioned by the retaining arm by the integrated function lever such that the functional cover is in the closed position, typically sealed at the mounting flange.

The head of the adjustment bolt is axially immovably held within the carrier and faces the functional cover, which is the condition after the opening provides access to the head of the adjustment bolt. After opening the function cover, the engineer can reach the adjustment bolts and use the tool to turn the adjustment bolts as needed.

The carrying device preferably includes a guiding arm that holds the guide, the connecting bolt being movable through the guide.

In a preferred embodiment, the retaining arms and/or the guiding arms are designed to be resiliently, telescopically or elastically held such that they can extend under the force. Thus, when the sliding door strikes the end stop, the force received by the guiding arm can be compensated by the retaining arm or the resilient element connected thereto.

In this way, the functionality of the external snubber device can be integrated into the mounting device of the present invention. However, a simple end stop can be provided in the running track.

The carrier device may be designed as one piece or may comprise a first carrier and a second carrier, the first carrier having a retaining arm preferably made of a known plastic, the second carrier having a metal preferably The guiding arm.

Designing the carrier in two parts advantageously allows the function of the carrier to be performed. In the first carrier made of plastic, an elastic retaining arm and an elastic catching element that interact with the second carrier can be used.

The second carrier made of metal may advantageously have a guide for stably seating and retaining the connecting bolt. In addition, the second carrier can advantageously have a stable shaped element, such as a mounting shoulder, by which the retaining device can be held in a shape-locking manner within the retaining device.

The two carriers can advantageously be connected in a form-locking manner to the elastic hitch element, which is arranged at the first holder and which can be engaged in a complementary hook element arranged at the second carrier .

Figure 1A shows a sliding device 100 of the present invention having an operating rail 3, two brackets 2 connected to the sliding door 4 by the first mounting device 10A and the second mounting device 10B of the present invention being guide. The distance between the sliding door 4 and the rotating track 3 is kept as small as possible in order to avoid interference with the air gap. Therefore, it is only possible to reach the mounting devices 10A, 10B from one side. However, such a passage advantageously has the mounting devices 10A and 10B of the present invention.

1B shows a portion of the sliding device 100 of FIG. 1A having a first mounting device 10A that includes a retaining rail 6 disposed within a recess 40 provided on the upper side 41 of the sliding door 4, and retained within the retaining rail 6. Hold device 1. The holding device 1 is connected to the main body 22 of the carrier 2 by means of a connecting bolt 5 which is guided in the running rail 3 by the rail wheel 22.

1B and 2A show the retaining rail 6 at a distance from the front side 42 of the sliding door 4 such that the inlet of the recess 40 can receive a mounting flange 16 provided at the retaining device 1, said mounting flange and retaining rail The front side portions of 6 overlap. If the bracket 2 hits an obstacle in the running rail 3, such as an end stop or a damping device, the force exerted by the sliding door will pass through the retaining rail 6, the mounting flange 16 and also through the retaining device 1, the connecting bolt 5 And the carriage 2 is transmitted to a buffering device (not shown) which receives and absorbs the force and the connection energy of the sliding door 4.

In the preferred embodiment described below, a resilient element that absorbs the kinetic energy of the sliding door 4 is incorporated into the holding device 1.

Figure 2A shows a first mounting device 10A with a holding device 1 inserted into a holding rail 6 (already taken out of the holding rail 6).

In the detail view D1 of Fig. 2C, the end portion of the holding device 1 of Fig. 2A is shown (see arrow D1).

In the detail view D2 of Fig. 2D, the end portion of the retaining rail 6 of Fig. 2A (see arrow D2) is shown, which is completely received by the recess 40 of the sliding element 4 and secured thereto by mounting bolts 65, said mounting The bolts are disposed within mounting holes 66 provided in the central portion 62 of the retaining rail 6 (see Figure 5A). It is also shown that the retaining rail 6 comprises two fixing elements 63a and 63b in the central portion 62 for receiving the retaining element 113, which can be fixed at selected locations within the retaining rail 6 by the securing elements. The fixing elements 63a, 63b are holes or recesses that are pressed into or into the retaining rail 6.

In the embodiment shown, the holding device 1 comprises a two-part carrier device 11, 12 having a first carrier 11, a second carrier 12, an adjustment bolt 13, a rail body 14 and a connection held by the track skid 15 A bolt 5 (see Fig. 5A), and the connecting bolt 5 includes an upper side connecting portion 53 that is rotated into the main body 21 of the bracket 2. The holding device 1 can be connected to the carrier 2 in a simple manner by means of a connecting bolt 5. By inserting the holding device 1 into the holding rail 6, a connection is established between the sliding element 4 and the carrier 2.

2C shows that the holding device 1 has a functional cover 19 at the end facing the front side 42 of the sliding element 4, which advantageously covers the mounting device 10A that is inserted into the sliding door 4. For example, as shown in FIG. 5A, the technician can reach the adjustment bolt 13 by opening the function cover 19.

FIG. 8A shows that the functional cover 19 includes two hinge holes 199 into which the hinge pins 119 disposed at the first carrier 11 can be coupled. Therefore, the functional cover 19 is rotatable and openable around the hinge pin 119.

FIG. 2C also shows that the first carrier 11 comprises a retaining arm 112 having a retaining element 113. The front side of the retaining element 113 is ramped such that when the retaining device 1 is moved into the retaining track 6 and the retaining element 113 is guided across the front side edge of the retaining track 6, the retaining arm 112 will automatically raise. The elastic retaining arm 112 is then tensioned, causing its guiding retaining element 113 to automatically enter the first securing element 63a. Therefore, the holding device 1 can be fixed in the holding rail 6 by a simple joining process. In order to release the holding device 1, the holding arm 112 can be raised again so that the holding member 113 can be separated from the fixing member 63a. Therefore, as the holding arm 112 is raised, the holding device 1 can be further inserted into or removed from the holding rail 6. It is also possible to additionally or alternatively use a retaining element which is arranged laterally or symmetrically, which can be engaged in a corresponding bore provided in the retaining rail 6.

In a preferred embodiment, the functional cover 19 is used to actuate the retaining arm 112. For this purpose, the functional cover 19 has a function lever 191 (see Fig. 8A) engaged with the guide arm 112 or the release lever 114 attached thereto.

Fig. 2B shows a section through the holding rail 6 in the range of the fixing member 63a along the line A-A shown in Figs. 2A and 3B.

In this embodiment, the retaining rail 6 comprises a U-shaped profile having a central portion 62 and side walls 61 connected thereto, with forming elements 611 on the sides facing each other, said forming elements being parallel to the longitudinal axis of the retaining rail 6 Extends and appears as a hook-shaped cross section. The shaping element 611 serves to hold the holding device 1 in a form-locking manner. The second carrier 12 of the holding device 1 comprises a plate-shaped guiding arm 122 having a mounting shoulder 123 on each of the two side walls. When the holding device 1 is inserted into the holding rail 6, the mounting shoulder 123 is guided along the forming element 611, so that the holding device 1 is held in a form-locking manner and can only move axially.

Figure 3A shows the holding device 1 of Figure 2B from the front side. A first carrier 11 having a retaining arm 112 and a second carrier 12 having a guiding arm 122 are shown, the second carrier comprising a guide 125 at the front end and a connecting bolt 5 connected to the track sled 15 at the lower end It is held in the guide member in a straight movable manner.

FIG. 3B shows the mounting device 10A of FIG. 2B with the holding device 1 inserted into the holding rail 6.

Fig. 3C shows a section of the holding device 1 of Fig. 3A taken along line B-B shown in Fig. 3A. The cut faces pass through the carrier means 11, 12 and show that their carriers 11, 12 enclose the bolt passages 130, which are rotatably supported and retained in the bolt passages.

Each of the two carriers 11, 12 comprises a carrier body 111, 112 having toothed elements 116, 126 that are joined to each other in a form-locking manner. The first carrier 11 also has a catching element 118 that engages within a connecting opening 129 provided in the second carrier 12 and is locked therein within the connecting seat 128.

Thus, the two carriers 11, 12 are connected to each other in a form-locking manner and can be released from each other only by releasing the catching elements 118.

The two carriers 11, 12 can be produced more easily than the monolithic carrier. The function of the two carriers 11, 12 can advantageously be implemented by selecting a suitable material. The first carrier 11 is preferably made of plastic such that a resilient retaining arm 112 can be made which is bendable for the purpose of releasing the retaining element 113, and preferably when the sliding door reaches the end stop, The kinetic energy of the sliding door 4 is absorbed and the holding arm can be extended, thus avoiding high loads and disturbing sounds on the components of the device.

Figure 4 shows the holding device 1 of Figure 3A with a first carrier 11 comprising a carrier channel 110 in which an adjustment bolt 13 is seated. Also shown is a toothed element 116 and a hitch element 118 that are integrally connected to the carrier body 111 of the first carrier 11. It is also shown that the functional cover 19 is connected to the first carrier 11. It is shown that once the functional cover 19 is opened, it can pass through the connecting flange 16 to reach the first carrier 11.

A second carrier 12 with a second carrier body 121 is shown separately, comprising a toothed element 126, a connection opening 129 and a guiding arm 122 with a mounting shoulder 123 provided on both sides thereof. The guiding arm 122 has a guide 125 with a guiding opening 1250 through which the connecting bolt 5 can be inserted into the holding device 1 at the front end.

The connecting bolt 5 includes a first connecting portion 51 that is inserted into the track skid 15, a second connecting portion 52 that is vertically movable within the guide member 125, and a second connectable portion that is connectable to the bracket 2 and preferably includes a bolt thread A third connecting portion 53 is rotatable into the body 21 of the associated bracket 2.

The track skid 15 slidably seated within the track body 14 includes a receiving opening 151 for receiving a first connection 51 of the connecting bolt 5, and a wing-shaped or cubic first guiding element 152A and a second on the opposite side Guide element 152B.

The rail body 14 includes a threaded member 141 having a threaded bore into which a bolt rod 132 of the adjustment bolt 13 can be engaged. The track body 14 also includes a first track wall 143A and a second track wall 143B having first and second track members 142A, 142B (142A not shown) on sides that face each other. The rail elements 142A, 142B formed as guide grooves or track slots inscribed in the rail walls 143A, 143B extend parallel to each other and are each inclined towards the longitudinal axis of the adjusting bolt 13 or the bolt axis y.

Figure 5A shows a section along the line C-C of the mounting device 10 of Figure 3B. The carrying devices 11, 12 are vertically connected along the bolt axis y. The head 131 of the adjustment bolt 13 and the bolt rod 132 are held between the first carrier 11 and the second carrier 12, and the bolt extends through the screw 141 into the rail body 14. The head 131 of the adjusting bolt 13 is rotationally held within the bolt seat 127 but is not axially movable within the bolt seat, which is formed in the second carrier 12. The bolt head 131 is also supported by a support body 117 provided on the first carrier 11.

The carrier means 11, 12 are held in a form-locking manner by a shaping element 611 and a guiding arm 122 which are arranged on the side wall 61 of the holding rail 6 and which are respectively adjacent to the second carrier 12 or the second carrier body 121 .

As shown in detail view D3 of Figure 5B (see arrow D3 in Figure 5A), the retaining device 1 is moved axially within the retaining track 6 until the retaining member 113 engages within the selected securing member 63a. In this detail view, the end portion of the retaining arm 112 is shown facing the functional cover 19 and has a catching element 113 and a release lever 114 that can interact with the functional lever 191 disposed on the functional cover 19.

The retaining element 113 includes a slanted side flap 630 at a side facing the retaining rail 6. When the holding device 1 is inserted into the holding rail 6, the side flaps 630 are guided over the upper front edge of the central portion 62 of the holding rail 6, and the holding arm 112 is thereby raised upward. By this means, the holding device 1 can be moved into the holding rail 6 without otherwise lifting the holding arm 112. Alternatively, the central portion 62 of the retaining rail 6 may have an inclined surface at the front side portion, and the retaining member 113 may slide over the inclined surface into the retaining rail 6 and at the same time lift the retaining arm 112. In this case, the holding member 113 that is sufficiently adapted to the fixing member 63a and fixedly held by the fixing member 63a can be used.

The detail view D4 of Fig. 5C shows the rail skid 15 of Fig. 5A (see arrow D4 in Fig. 5A), in which the first connecting portion 51 of the connecting bolt 5 is firmly held or rotatably held. The second connecting portion 52 is slidably held within the guide 125 along the guiding axis x. Therefore, the connecting bolt 5 is held such that it can move only along the guiding axis x and thus perpendicular to the bolt axis. Also shown is a track wall 143B having a channel-type track element 142B into which the second guide element 152B of the track skid 15 is engaged.

Figure 6A shows a cross-sectional view of a track body 14 having a second track element 142B that appears as a rectangular cross section and completely passes through the second track wall 143B from the bottom to the top. A track skid is also shown which moves vertically as soon as the track body 14 is leveled.

Figure 6B shows the complete rail sled 15 of Figure 6A including a receiving opening 151 for connecting the bolts 5 and two guiding elements 152A, 152B on opposite sides. In this preferred embodiment, the guiding elements 152A, 152B are retained in the shape-locking manner within the track members 142A, 142B and are only movable in a straight line.

Figure 7A shows a cross-sectional view of the mounting device 10 of Figure 5A with a track sled 15 and a connecting bolt 5 that is moved to the lowermost.

Figure 7B shows a cross-sectional view of the mounting device 10 of Figure 5A with the track skid 15 and the attachment bolts 5 at the intermediate height.

Figure 7C shows a cross-sectional view of the mounting device 10 of Figure 5A with the track skid 15 and the connecting bolt 5 moved to the top.

It is shown that the connecting bolt 5 moves only axially along the guiding axis x, while the rail body 14 only moves axially along the bolt axis y.

Figure 8A shows the first carrier 11 of Figure 4 as seen from the rear side after removal of the functional cover 19. It is shown that the mounting flange 16 is composed of two cylindrical members having, at the lower end, hinged pins 119 that are directed toward each other and engageable within an opening 199 of the functional cover 19. The functional cover 19 held by the hinge pin 119 includes a function lever 191 and it interacts with a release lever 114 provided at the front of the holding arm 112.

FIG. 8B shows another embodiment of the first carrier 11 of FIG. 8A having a bendable and extendable retaining arm 112. The retaining arms 112 are S-shaped and thus extendable. At the same time, the end portion of the holding arm 112 can be raised by the function lever 191 to separate the holding member 113 from the fixing member 63a or 63b.

In connection with Figure 5C, it is mentioned that the first connecting portion 51 of the connecting bolt 5 is preferably held in rotation within the track skid 15.

Figure 9 shows, in a preferred embodiment, the rear end of the retaining device of Figure 5A with a connecting bolt 5 having a tool connection 54 between the first connecting portion 51 and the third connecting portion 53. The connecting bolt 5 is clamped at the tool connecting portion 54 by the bolt wrench T1 and rotated as needed.

A second tool connecting portion 55 is provided at the lower end of the connecting bolt 5, and the bolt driver tool T2 can be inserted into the second tool connecting portion to rotate the connecting bolt 5.

Therefore, the holding device 1 can be easily connected to the bracket already installed in the running rail by manually or using the first tool T1 or the second tool T2 to transfer the connecting bolt 5 into the bracket main body. Preferably, such a connecting bolt is adjusted when the track sled 15 is in a position at about half of the height within the rail body 14 as shown in Figure 7B or Figure 9. After the holding device 1 is mounted, the rail skid 15 is mounted in the middle of the adjustment range through which the adjusting bolt 13 is driven. In the case where the track skid 15 subsequently reaches the edge of the adjustment range, the track skid 15 can be easily returned to the middle range by driving the first tool T1.

In order to connect the connecting bolt 5 to the rail skid 15, the first connecting portion 51 has an annular groove 511 in which a plurality of retaining seats 512 are provided. A bolt-shaped connecting element 7 having a spring passage 71 and an elastic load ball 72 is inserted into the track skid 15 which is pressed into the adjacent retaining seat 512. When the connecting bolt 5 is rotated, for example, after the connecting bolt 5 is rotated for a half cycle or a quarter of a week, the elastic load ball 72 is pushed out of the retaining seat 512 and can enter the next retaining seat 512. Thus, in this preferred embodiment, the connecting bolt 5 can be stepped from the first position to the second position and correspondingly fixed again.

Figure 10A shows a cross-sectional view of the connecting bolt 5 and the track sled 15 of Figure 9 during installation. The forked skid 15 includes a retaining flange 155 having a U-shaped profile with struts extending in parallel and inclined toward the bolt axis y to form an inlet ramp 154. Therefore, the first connecting portion 51 of the connecting bolt 5 can be inserted obliquely into the rail sled 15 along the entrance ramp 154 and then vertically aligned. The retaining flange 155 is engaged into the annular groove 511 provided in the first connecting portion 51. Subsequently, the inclined inlet ramp 154 prevents the connecting bolt 5 from being separated from the retaining flange 155.

Thus, the forked embodiment of the track skid 15 allows receiving the connecting bolt 5 designed as a separate part and rotationally retaining the connecting bolt 5 within the annular groove 511.

It should be noted that a plurality of interacting device components can be interchanged without changing the function of the interaction. For example, the connecting bolt 5 may also have a retaining flange, and the rail sled 15 may have a retaining groove. Furthermore, embodiments of the guiding element 152 of the track skid 15 and the embodiment of the track element 142 of the track body 14 can be interchanged.

Figure 10B shows a cross-sectional view of the connecting bolt 5 and the forked track sled 15 of Figure 10A after installation, after which the resilient load ball 72 of the connecting element 7 engages in the retaining seat 512 of the connecting bolt 5, the connecting bolt 5 is fixed by this.

Figure 10C shows a partial view of the connecting bolt 5 of Figure 10B and the forked track skid 15. [References] [1] EP0818598A1 [2] WO2011063535A1 [3] WO2011161707A1 [4] WO9738198A1 [5] DE3338146A1 [6] WO2004040091A1
